Xiaomi Mi 9T Pro Screen Replacement

Introduction

Use this guide to replace a cracked or broken screen on your Xiaomi Mi 9T Pro.

If the frame is deformed, it's important to replace it to make sure the new screen will mount correctly and won’t suffer damage from uneven pressure.

If your battery is swollen, take appropriate precautions. Before disassembling your device, discharge the battery below 25%. The battery can catch fire and/or explode if accidentally punctured, but the chances of that happening are much lower if discharged.

Note: This guide instructs you to replace only the screen while leaving the original frame and motherboard in place. However, some replacement screens for this phone come pre-installed in a new frame (a.k.a. chassis), which requires a very different procedure. Make sure you have the correct part before starting this guide.

Before you begin this procedure, be sure to have a set of replacement adhesives for both the rear glass and the screen.

What you need

  1. Xiaomi Mi 9T Pro Screen Replacement, Heat the rear glass: step 1, image 1 of 1

    • Prepare an iOpener and apply it to the rear glass for at least two minutes to loosen the adhesive underneath.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are both susceptible to heat damage.

    • Secure a suction handle to the bottom edge of the rear glass, as close to the edge as possible.

    • If the rear glass is cracked, the suction handle may not stick. Try lifting it with strong tape, or superglue the suction handle in place and allow it to cure so you can proceed.

    • Lift the rear glass with the suction handle to create a small gap between the back cover and the frame.

    • If you have trouble creating a gap, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.

    • Insert an opening pick into the gap you created.

    • Slide the opening pick to the bottom right corner to slice the adhesive.

    • Leave the opening pick in place to prevent the adhesive from resealing.

    • If the adhesive becomes hard to cut, it has most likely cooled down. Use your iOpener for one to two minutes to reheat it.

    • Insert a third opening pick at the bottom left corner of your phone.

    • Slide the opening pick along the left edge of your phone to slice the adhesive.

    • Leave the opening pick in the top left corner to prevent the adhesive from resealing.

    • Insert a fifth opening pick underneath the top right corner.

    • Slide the opening pick along the right edge of the rear glass to slice the remaining adhesive.

    • Do not try to remove the rear glass all the way yet. It might be adhered to the phone assembly because of the adhesive around the rear camera.

    • Carefully try to separate the rear glass from the phone assembly. If you're successful you can ignore this step. In case the rear glass sticks to the rear camera adhesive, continue with this step.

    • Carefully insert a plastic or playing card at the right edge of the phone where the rear camera is located.

    • Use the plastic card to slice the adhesive along the rear camera frame.

    • Remove the rear glass.

    • Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

    • Secure the new rear glass with pre-cut adhesive or double-sided adhesive tape. After installing the rear glass, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond—a stack of heavy books works well.

    • Once the screen is warm to the touch, apply a suction handle to the bottom edge of the screen.

    • If your screen is badly cracked, covering it with a layer of clear packing tape may allow the suction handle to adhere. Alternatively, very strong tape may be used instead of the suction handle. If all else fails, you can superglue the suction handle to the screen.

    • Insert an opening pick into the gap between the midframe and the screen.

Conclusion

If possible, turn on your device and test your repair before installing new adhesive and resealing.

To reassemble your device, follow these instructions in reverse order.

The best way to secure the new screen is to apply a sheet of custom-cut double-sided tape to the back of the screen.

Take your e-waste to an R2 or e-Stewards certified recycler.

Wer wie ich vor der Herausforderung steht, ein Display inklusive Rahmen zu wechseln, dann wird man schnell feststellen, dass man den Akku ausbauen muss, welcher verklebt ist, was sehr gut funktioniert ist, das gesamte Telefon zu erhitzen, ich nutze dafür meinen 3d Drucker mit Platte auf 50°C.

Lasse das Handy dann einfach drauf und sobald der Akku warm ist (35-40° heißer würde ich definitiv nicht empfehlen - vielleicht noch 45) kann man den Akku ohne zerstörung, ohne großen Aufwand problemlos entfernen, dazu auf der rechten Seite die 3 Klebestreifen lösen und auf der linken Seite ebenfalls, rechts dann am mittleren Element ziehen da bei 1 und 2 der kleber befestigt ist, an 3 nur der Akku, die Kraft ist schwer zu beschreiben, aber wirklich nur ganz leicht ziehen.

Dann kann man den Akku durchaus nochmal benutzen. Wenn der Akku irgendwie beschädigt werden sollte, verbogen etc, auf keinen Fall weiternutzen, nur wenn der wirklich unbeschädigt ist.

Hallo Dominik,

ich habe deine Anleitung befolgt und stehe nun vor einem nahezu perfekten Endergebnis. Nahezu perfekt, weil irgendwie nur meine obere Hälfte des Displays reagiert. Was könnte ich bei der Reparatur falsch gemacht haben? Einen Pin von einem Stecker zerstört? Oder ist das neue Display schon fehlerhaft bei mir angeliefert worden? Hast du da schon Erfahrungen gemacht? Grüße Mats
